How do I re-encode WebM to MPG without losing video quality?
+
Upload your WebM file and the converter runs a CRF-based re-encode targeting visually-lossless MPG output (CRF 18 by default, lower values = larger file / higher quality). The codec is chosen to match the MPG container — H.264 for broad-compat MP4, H.265 for size-efficient MKV, VP9 for WebM, AV1 for newer pipelines.
Which video codec does the MPG output use?
+
It depends on the MPG container. MP4 defaults to H.264 for the broadest playback support across phones, browsers, and Smart TVs. MKV defaults to H.265 / HEVC for roughly half the file size at equivalent quality. WebM defaults to VP9. The advanced options expose explicit codec choice if you need to override.
Will my audio track survive WebM to MPG conversion?
+
Yes. When WebM and MPG share an audio codec (e.g. both carry AAC), audio is re-muxed with no re-encode — bit-identical. When the codecs differ, audio is transcoded to AAC / Opus / Vorbis depending on what the MPG container supports. Multi-track audio (commentary, alternate languages) is preserved.
Can I keep the original framerate when converting WebM to MPG?
+
By default yes — a 24fps WebM stays 24fps in MPG; a 60fps WebM stays 60fps. If you need to change rate (e.g. interlaced 29.97 → progressive 30, or 60 → 30 for upload limits), the framerate option handles 3:2 pulldown, deinterlacing, and frame-blending in the same encode pass.
How much will the file size change going from WebM to MPG?
+
Same-codec re-mux (WebM H.264 → MPG H.264 just changing container): nearly identical size. Codec change can swing dramatically: H.264 → H.265 typically halves the file at the same visual quality; VP9 is roughly comparable; AV1 cuts another 20-30% but is slower to encode.
Will the MPG file play on iPhone, Android, and Smart TVs?
+
MP4 / H.264 plays natively on every modern device. MOV / H.264 plays on Apple devices and most TVs but not always on older Android. MKV needs VLC on iOS. WebM is browser-first. The advanced options include a "device compatibility" preset that picks the safest MPG codec / container for your target.
How long does converting a 1-hour WebM video to MPG take?
+
Same-codec re-mux is near-instant — 30 to 60 seconds for a 1-hour file. A full codec re-encode runs at roughly 0.3-0.7x source duration on our GPU pipeline, so a 1-hour WebM → MPG finishes in 18-40 minutes depending on resolution and target codec.
What is the maximum resolution supported for WebM to MPG?
+
Up to 8K (7680×4320) on Premium plans. Free conversions are capped at 4K (3840×2160) by the per-file size limit. HDR metadata (HDR10, HDR10+, Dolby Vision when present) is carried through where both WebM and MPG containers support it.
Is my WebM video private during conversion to MPG?
+
Yes. Uploaded video files are processed in isolated workers, never viewed by a human, never indexed, and deleted within minutes of completion. The retention window is documented at /privacy/ and we publish no training corpus from user uploads.
Can I crop, trim, or rotate during the WebM to MPG conversion?
+
Not in the same step — use /video-trim/ or /video-cutter/ to clip first, then run the WebM → MPG conversion. Chaining trim and convert is faster than re-encoding the entire WebM just to drop unused footage.
Why is the MPG file blurry compared to the WebM source?
+
Almost always a bitrate-too-low setting. Re-encoding from a high-bitrate WebM into a default-CRF MPG compresses heavily on motion-rich scenes. Push CRF down to 16-18, or set an explicit target bitrate matched to the WebM source, and the MPG regains its clarity.
Does the WebM to MPG converter handle subtitles?
+
Yes — embedded subtitle tracks (mov_text in MP4, SRT/ASS in MKV) are preserved when both WebM and MPG containers support them. Burned-in (hardsub) subtitles transfer automatically because they live in the video frame itself.
